Prostaglandin E1 prevents histopathological changes improving renal function in experimental nephropathy induced by renal microembolism.

This study investigated the effect of prostaglandin E1 (PGE-1) treatment on the biochemical and histopathological changes in a model of nephropathy that was induced using renal microembolism in rats. Wistar rats were assigned to three groups: a control group (C, normal), a renal microembolism (RM) group, and a renal microembolism treated with PGE-1 (RM + PGE-1) group. The renal microembolism was induced by an arterial injection of polymethylmethacrylate microbeads into the remaining kidney of nephrectomized rats.

Anti-inflammatory Effect of Low-Dose Anethole and Ibuprofen Combination Is Accompanied by Partial Prevention of Hepatic Metabolic Changes in Arthritic Rats.

Anethole (AN) is a natural compound that has attracted great scientific interest because of its numerous biological activities, including anti-inflammatory effects. However, these effects were obtained with high doses of AN, which may be one limitation of its therapeutic use. This study evaluated the effects of a low-dose AN and ibuprofen (IB) combination on inflammatory parameters in Freund's complete adjuvant-induced arthritis (AIA) and arthritis-induced hepatic metabolic changes.

Nephropathy induced by renal microembolism: a characterization of biochemical and histopathological changes in rats.

The aim of this study was to investigate some biochemical parameters of renal function and the vascular, glomerular, tubular, and interstitial manifestations in the progression of nephropathy induced by renal microembolism. Renal microembolism was induced by the arterial injection of polymethacrylate microspheres in the remnant kidney of nephrectomized rats. Animals 110-120 days old were randomly divided into three groups: the control group (C; normal), the nephrectomized group (S; nephrectomized that did not undergo renal microembolism), and the model group (M, nephrectomized animals that underwent renal arterial microembolism).

Behçet's Disease: Pulmonary Aneurysm Resolution with Oral Therapy and HLA B72 Allele Association.

We report the case of a woman who was diagnosed with a pulmonary artery aneurysm that was caused by Behçet's disease. The patient was initially diagnosed with community-acquired pneumonia and then pulmonary thromboembolism and aneurysm of the right pulmonary artery segmental branch was confirmed. The initial treatment consisted of anticoagulant drugs.

Evaluation of the in vivo acute antiinflammatory response of curcumin-loaded nanoparticles.

Curcumin is the main curcuminoid found in turmeric rhizomes and is a strong candidate to formulate foodstuff with specific properties. Among various bioactive properties of curcumin, its antiinflammatory activity is remarkable; on the other hand, its low water solubility leads to low absorption. Thus, new formulations need to be developed to improve its efficacy, and encapsulation is a promising alternative strategy in this regard.

Acetaminophen-induced hepatotoxicity: Preventive effect of trans anethole.

The hepatotoxicity induced by APAP is caused by the excessive production of N-acetyl-para-benzoquinone imine (NAPQI), which, when reacting with hepatic proteins proved to cause irreversible lesions. Associated with this process, an intense inflammatory process is also evidenced, characterized by the increased cell influx and production/release of inflammatory mediators. Trans anethole, an aromatic compounds has been showed anti-inflammatory efficacy by inhibit the cellular recruitment and synthesis/releases of many proinflammatory mediators such as prostaglandin (PGE), cytokines (TNF, IL-1) and nitrico oxide (NO).

Canova medication changes TNF-α and IL-10 serum levels in mice infected with Trypanosoma cruzi Y strain.

Objective: To identify whether Canova medication changes TNF-α and IL-10 serum levels in mice infected with Trypanosoma cruzi Y strain.

Methods: Animals were divided into five groups: non-treated infected animals (I); benznidazole-treated infected animals (Bz; 100 mg/kg body weight, single daily dose by gavage); Canova medication (CM) treated infected animals (CM; 0.2 mL/animal, single daily dose by gavage); benznidazole- and Canova medication-treated infected animals with the above-mentioned dose (Bz+CM); and non-infected animals (C).

Hydroethanolic extract of Smallanthus sonchifolius leaves improves hyperglycemia of streptozotocin induced neonatal diabetic rats.

Objective: To evaluate the effect of hydroethanolic extract of yacon on the hyperglycemia induced by streptozotocin (STZ) in neonatal rats.

Methods: Wistar rats aged two days old received an intraperitoneal injection of STZ (160 mg/kg); after seven weeks, glycosuria was determined and animals with glucose levels above 250 mg/dL were included in the study. Groups of diabetic and non-diabetic rats were treated orally with yacon extract at a dose of 400 mg/kg/d for 14 d.

Involvement of cytokines in the modulation and progression of renal fibrosis induced by unilateral ureteral obstruction in C57BL/6 mice: effects of thalidomide and dexamethasone.

This study investigated the kinetics of cytokines that are involved in the development of interstitial fibrosis in mice that were subjected to UUO, the interstitial type I and III collagen deposition, and the effects of Thalido and Dexa treatment on these parameters. Inbred C57BL/6 mice were divided into the groups: Normal (not submitted surgery), Sham (sham surgery), Control (UUO treated with 0.5% carboxymethyl cellulose), Thalido (UUO treated with 5 mg/kg thalidomide), and Dexa (UUO treated with 1 mg/kg dexamethasone).

Hepatoprotective Effect of Silymarin (Silybum marianum) on Hepatotoxicity Induced by Acetaminophen in Spontaneously Hypertensive Rats.

This study was aimed to investigate the effect of Silymarin (SLM) on the hypertension state and the liver function changes induced by acetaminophen (APAP) in spontaneously hypertensive rat (SHR). Animals normotensive (N) or hypertensive (SHR) were treated or not with APAP (3 g/kg, oral) or previously treated with SLM. Twelve hours after APAP administration, plasmatic levels of liver function markers: alanine aminotransferase (ALT), aspartate aminotransferase (AST), glucose (GLU), gamma glutamyl transferase (γ-GT), and alkaline phosphatase (ALP) of all groups, were determined.

Inhibitory Effect of the Hexane Fraction of the Ethanolic Extract of the Fruits of Pterodon pubescens Benth in Acute and Chronic Inflammation.

Fruits of Pterodon pubescens Benth have been used traditionally for the treatment of rheumatism, sore throat, and respiratory disorders, and also as anti-inflammatory, analgesic, depurative, tonic, and hypoglycemic agent. The study was aimed at evaluating the anti-inflammatory activity of the hexane fraction of an ethanolic extract of P. pubescens fruits.
